' This inventionrelates to a web-guide for rewii'iding-machines',ctc. and its object is to provide means for guiding and alining a trav-v wiiiding drums or rollers, which is generally "known in the art an d tov the trade as a sur face`winder., l

Such a machine is shown in UnitedStahw` Letters Patent to Francis Meisel, No. 492,9i'isi, patented March' 7, 1893, to mayT be had for a fuller tails of the slitting only. such features being shown an scribed asis necessary for a standing of the application of vention.

It will be obvious that the character of the grooves in the idler-rollers and in the windingdrums may vary Iwidely without departing from the scope of 'this invention.
